Answer:
x^3 - 5 x^2 + 2 x + 8 = 0
Step-by-step explanation:
Solve for x over the real numbers:
x^3 - 5 x^2 + 2 x + 8 = 0
The left hand side factors into a product with three terms:
(x - 4) (x - 2) (x + 1) = 0
Split into three equations:
x - 4 = 0 or x - 2 = 0 or x + 1 = 0
Add 4 to both sides:
x = 4 or x - 2 = 0 or x + 1 = 0
Add 2 to both sides:
x = 4 or x = 2 or x + 1 = 0
Subtract 1 from both sides:
Answer: x = 4 or x = 2 or x = -1
Answer:
7/8
Step-by-step explanation:
1 1/4 is the same as 5/4.
5/4 is also the same as 10/8.
The distance from 3/8 to 10/8 is 7/8.

Hello!
First you have to find the ratio
To find this you put the sides of the triangles in a ratio and simplify it
Make sure you do the same side on each triangle
12 : 8
6:4
3:2
The ratio is 3:2
We do not know all three sides so we can use the SSS postulate
This tells use the answer is the SAS postulate with a ratio of 3:2
The answer is D) SAS; 3:2
Hope this helps!
